Quick python script for compiling all .cpp files in a folder and subfolders with G++ (A simple, lazy makefile in Python)

gcc_compile.py

# Recursively finds all .cpp files within the current directory,
# and compiles them, printing any messages generated by g++ and writing the
# output to the bin folder.
from pathlib import Path
import os
import subprocess

bin_path  = 'bin/output'
file_list = []      # The list of .cpp files to be compiled

for a_file in Path('.').glob('**/*.cpp'):
    file_list.append(str(a_file))

cpp_file_sep = ' '
command = 'g++ -I./ ' + cpp_file_sep.join(file_list) + ' -o ' + bin_path

print(subprocess.getoutput(command))
